Many of the 3D printed homes and structures we've seen use concrete and - frankly - are a bit heavy. Making large squares out of concrete isn't that hard and while we're sure there's some benefit, it's not overwhelming. [Andy Coward] Apparently felt the same way and set out to find ways in which 3D printing could offer unique advantages in building structures. Result: a beam that would be difficult to make with conventional techniques But it's easy to make with a printer. The advantage is that it uses 78% less concrete than conventional beams with similar properties.
The key is that in a typical beam, not much concrete is bearing a significant load. This is simply because you need some concrete on one side of the beam and then some more on the other side. In the center, surprisingly little concrete really supports anything. The new beam takes advantage of this with steel reinforcement at a strategic point. Nevertheless, it uses 70% less steel than a typical reinforced beam.
There are many benefits to reducing content. Low transportation costs and low carbon production are among them. Beams also have built-in voids that can allow for services such as electricity and water. You can see a nice diagram of how it all goes together on the minimas' Website, remove unnecessary material hardly any new technology, Undoubted. We also see this often in metal 3D printing.
